Upgrade Catalyst Clash Arena

MaxB123_1

The summoner trials and basic/featured arenas have been updated in the past and offer nice units, battleships and gold.

However the rewards for the catalyst arena seemingly haven't been changed for a while, for example 500 gold as a first milestone. I don't know if many people do the catalyst arenas, but could they be made more appealing in the near future by improving the rewards on offer?
